Rory McIlroy has the chance to let his golf do the talking against Phil Mickelson in the opening session of the Ryder Cup, in a match US captain Tom Watson predicted should be a "barn-burner".

Mickelson joked on Wednesday about McIlroy's court case against the Northern Irishman's former management company Horizon, which has seen team-mate Graeme McDowell dragged into the dispute as he is still represented by them.

"Not only are we able to play together, we also don't litigate against each other and that's a real plus," said five-time major winner Mickelson.

McIlroy and the rest of the European team laughed off the remarks, with the world number one revealing he had landed a few verbal "jabs" on the left-hander at the gala dinner in Glasgow.

So perhaps it was appropriate that Watson also described the final morning fourball between McIlroy and Sergio Garcia and Mickelson and Keegan Bradley as the "main event in the first round".

"That last contest is the striking contest," added Watson, who was also captain in the 1993 when the United States last won on European soil at The Belfry. "We are looking forward to that."

Mickelson and Bradley won all three of their matches together two years ago and Watson put another successful Medinah pairing, Webb Simpson and Masters champion Bubba Watson, out first against Justin Rose and Henrik Stenson.

Thomas Bjorn and Martin Kaymer take on Jimmy Walker and Rickie Fowler in the second match, with local favourite Stephen Gallacher and Ryder Cup talisman Ian Poulter out third against young rookie pairing Jordan Spieth, 21, and Patrick Reed, 24.

Watson left out Jim Furyk, Matt Kuchar, Hunter Mahan and Zach Johnson but said all four would play in the afternoon foursomes, while European captain Paul McGinley said it was his intention to play Lee Westwood, Graeme McDowell, Victor Dubuisson and Jamie Donaldson, although it was not "written in stone."

"I've gone with one rookie in the morning and Tom has gone with three. That might be a genius move by Tom, it might not," McGinley said.

" My ideas might backfire, as well, but that's what you do as captain, make your decisions, set out your stall, watch what happens and you adapt to what happens.

"There will be decisions I'll get wrong as captain, I'm prepared for that. But I'd like to think that I'll be able to adjust things and go forward."

All four of Europe's pairs have not played together in the Ryder Cup before, with McGinley revealing that McIlroy and Garcia had been asking for months to be paired up.

" These guys all know each other very well and you move forward," said McGinley, who had spoken all week about not changing the successful European template. "Two years down the road, a different view and take on things, and games have evolved in slightly different ways and guys become more experienced.

"Ian Poulter is a very experienced player now. There's going to be a big atmosphere in that group, we'll need a guy with a big attitude for that and I think Ian Poulter fits that bill.

"Justin and Henrik spent a lot of time together at Lake Nona (in Orlando) over the years, know each other very, very well, and you have Sergio and Rory who have formed a real bond and friendship and respect for each other's games during the summer period.

"Things evolve and move. The template doesn't mean pairings have to be the exact same pairings."

McIlroy and Garcia did battle for the Open Championship and WGC-Bridgestone Invitational - both won by McIlroy - in the space of three weeks, but McGinley added of their pairing: "I probably wouldn't have seen it to be honest. They kind of raised it to me around BMW time in Wentworth (in May) and I said, okay, let me think about that.

"I didn't really pay a lot of attention to it and it's only as they started talking to me more and more around Firestone that my position became a little bit clearer."

US Open champion Kaymer hailed Bjorn as his "mentor" after the Dane's influence on him while vice-captain in 2010 and 2012, the latter contest ending in Kaymer holing the putt to ensure Europe would retain the trophy.

"Actually before we even qualified, we said we have to make the team so we can play with each other," Kaymer said.

"He was on the team earlier than me. I just needed to make sure to be on the team. And after the US Open, when he called me, I said maybe we get paired and we can play together."

Unsurprisingly, Poulter - who has won 12 of his 15 Ryder Cup matches and 11 of the last 12 - said he was "absolutely buzzing" at the prospect of playing alongside fellow wild card Gallacher, who lives just 35 miles from the course.

But Watson said he had no fears that Spieth and Reed would be intimidated, adding: "These kids are tough kids and they are not dumb.

"They know Ian has that reputation of being a great Ryder Cup player. If they beat him, it's more power to them.

"Same thing about the last group there. If Phil and Keegan win that match, just think of the boost it will give our team."

McIlroy explained how he got his own back on Mickelson over the litigation quip.

''I got a couple of jabs back at him at the gala dinner,'' McIlroy told the Golf Channel.

''I know Phil well and we had a couple of laughs about it. We took it well.

''Myself and G-Mac confronted him at the gala dinner and it was all good fun.''
